The management of generating source was studied for effective treatment and disposal of municipal solid waste (MSW). Two house with boiler using briquette, one apartment with central heating system were selected in this study as generating source. Generation rate, composition and properties such as moisture, volatile solid (V.S.), fixed solid (F.S.) and lower heaing value (LHV) of each materials in the MSW were measured weekly from January 1 to December 31 in 1985. From this experimental results, the following conclusions were obtained. 1) The annually average generation rate of MSW was 377g/cap ·day in the case of apartment and 1,350g/cap ·day in the case of house which involved briquette ash in 75wt%. 2) As the generation rate changes in a large range in our country (the number of month within 15% above or below yearly mean were more than 33%), it is very difficult to determine the size of collection and treatment facilities. 3) It was possible to recover directly papers and plastic to 90% and 80% of them respectely from the generating source. In this case, the waste resources could be with good quality within 10% moisture content. 4) The weight proportions of garbages (vegetable, food and fruits) and plastic were 46.9 and 9.7wt% in annually average respectively, which were higher than those in other country. The moisture content and V.S. content of MSW were 45.3 and 41.4/wt% in annually average. 5) The lower heating value of MSW was measured to be 2,170 kcal/kg in wet basis after briquette separation, but to go down 800 kcal/kg after papers and plastic recovery. 6) The equations for estimating LHV in wet basis were obtained in equation (7) and (8). This equation was found to be more correct than other equations. LHV = 4,500Vc + 9,500Vp - 600W[kcal/kg]··········· (7) LHV = 7,260Pi + 2,950Pa + ?? + 4,000Pc - 600W[kcal/kg]····(8)
